Ten Frame Cards – Numbers Greater than 10

Add numbers concretely using ten frame cards to build a ten first, then calculate how many ones are left. The student brings the two parts together to make the

whole. Next slide shows the example with 8 + 5.

Then, show students branching a ten. Then, teach students to make a ten mentally.

Race to $1.00 and variations

Students play this game (alone or in groups up to 4) with dimes and pennies.

They will roll a die exactly 7 times. They must roll all 7. For each roll, they must decide if they want to use dimes

or pennies for that particular roll. The winner is the person to get closest to $1.00 without

going over. My total $ _____________ . Amount to $1.00 _____________

Variation: Play with place value disks. Race to 100 or Race to

1000 (Play with 100 and 1000)

with any operation. After students have created a way to make one, repeat

the above steps for the number two. The activity is completed when the class has made every

number on the board in order.
